True Tech Ignition KS98T Knock Sensor

The True Tech Ignition KS98T is an ignition knock (detonation) sensor designed to monitor and protect your engine from damaging detonation. This sensor detects vibrations caused by engine knock or ping—the uncontrolled combustion of the air-fuel mixture in the cylinders—and sends a voltage signal to the engine control module (ECM) or powertrain control module (PCM).

Key Features:

• Piezoelectric crystal design generates accurate voltage signals when detecting engine knock
• Direct replacement for OEM knock sensors on select vehicles
• Bolt-on mounting with plug-in connector design for easy installation
• Helps ECM optimize ignition timing to eliminate knock and maximize performance
• Prevents power loss, reduced fuel economy, and potential engine damage
• Manufactured by Standard Motor Products under the True Tech Ignition brand

A properly functioning knock sensor is critical for modern engine management systems. When knock is detected, the ECM adjusts ignition timing to prevent detonation that can cause internal engine damage. A failed knock sensor can trigger the check engine light, reduce fuel economy, decrease performance under load, and allow prolonged knock that damages pistons and cylinder walls. The KS98T provides reliable, maintenance-free operation to keep your engine running efficiently and safely.
